This question is about force, mass and acceleration.
An automated delivery drone starts from rest and accelerates vertically upwards at 5.2 m/s25.2\text{ m/s}^25.2 m/s2.
Use the equation: Acceleration=Change in velocityTime taken\text{Acceleration} = \frac{\text{Change in velocity}}{\text{Time taken}}Acceleration=Time takenChange in velocity
Calculate the velocity of the drone after 12.5 s12.5\text{ s}12.5 s.
A cargo-carrying robotic cart moves along a flat conveyor track with an acceleration of 1.6 m/s21.6\text{ m/s}^21.6 m/s2.
The net force acting on the cart and its cargo is 384 N384\text{ N}384 N.
Harnessing Newton's second law, calculate the total mass of the robotic cart and its cargo.
